"A quartet from Rome, though their singer Vincenzo 'Lord Enzo' Massetti came from Naples, they debuted with a single in 1971. The album, simply called I Teoremi, is one of the rarest Italian prog-era albums, though not a proper prog LP, as it contains a hard rock inspired sound in the same style as early Rovescio della Medaglia. It was released in 1972 on the small Polaris label, that also produced the Alpha ralpha boulevard LP by I Numi, and contains seven self-penned tracks, mostly in the hard rock vein, with light prog influences as in the long 'Mare della tranquillita', the only track including piano. A very good album whose original copies are worth a fortune. An incredibly rare album, this reissue is a perfect replica of the original one, with a textured gatefold cover and a flap on the right side as the original."
